There is a new connective
`tc_opaque`
, which can be used to make definitions
opaque for type classes, and thus opaque for most tactics of the proof
mode.

Many missing type class instances for distributing connectives have been
defined.

The tactics
`iIntros (?)`
and
`iIntros "!#"`
(i.e.
`iAlways`
) are now
implemented using type classes. That way, they are more generic, e.g.
`iIntros (?)`
also works when the universal quantifier is below a modality,
and
`iAlways`
also works for the plainness modality. A breaking change,
however, is that these tactics now no longer work when the universal
quantifier or modality is behind a type class opaque definition.
Furthermore, this can change the name of anonymous identifiers introduced
with the "%" pattern.
*
The generic
`fill`
operation of the
`ectxi_language`
construct has been
defined in terms of a left fold instead of a right fold. This gives rise to
more definitional equalities.
*
The big operators have been improved:

of evars, which often led to divergence. There are a few places where type
